Why don't use area_light?

An area_light ,even with a high density, with the adaptive option can be 
relatively fast.

Try this, rather extreme, one:
light_source{<40, 80, -40> rgb 1 area_light 8*x, 8*z, 257, 257 adaptive 
0 circular orient}
No real need to use jitter with that density.

And compare it to the proposed one from the insert menu.

light_source {<0,0,0> color rgb 1.0
   area_light <8, 0, 0> <0, 0, 8> 4, 4
   jitter circular orient translate <40, 80, -40>
}

Both cover the same area.
